Finding friends for multiuser online games

ABSTRACT

The present disclosure relates to games and applications in general and in particular to computer-implemented online games, such as online role-playing games, playable by more than one person from more than one location. The game engine can search a player&#39;s social network to find friends to play with. These social networks can be constructed implicitly by analyzing a player&#39;s game play information and other information.

TECHNICAL FIELD

The present disclosure relates to games and applications in general andin particular to computer-implemented online games, such as onlinerole-playing games (RPGs), playable by more than one person from morethan one location.

BACKGROUND

In many games, there is a virtual world or some other imagined playingspace and a player of the game controls one or more player characters(herein “character,” “player character,” or “PC”). Player characters canbe considered in-game representations of the controlling player; assuch, all uses of the terms “player,” “user,” “entity,” and “friend”refer to the in-game player character controlled by that player, user,entity, or friend, unless context suggests otherwise. The game displaycan display a representation of the player character. A game engineaccepts inputs from the player, determines player character actions,decides outcomes of events and presents the player with a game displayilluminating what happened. In some games, there are multiple players,wherein each player controls one or more player characters.

An electronic social networking system typically operates with a socialnetworking server or servers providing interaction between users suchthat a user can specify other users of the social networking system as“friends.” As should be apparent, a collection of users and the “friend”connections between users can form a social graph that can be traversedto find second, third and more remote connections between users, muchlike a graph of nodes connected by edges can be traversed.

Certain online gaming systems allow for users, using suitable userdevices (computers, consoles, etc.) networked to each other, directly orindirectly, to play games with or against other users. Some games havefeatures to assist users in forming a group around specific content suchas World of Warcraft's™ “Looking for Group” (LFG) and “Looking for More”(LFM) features for grouping users around specific content, e.g., aspecific game instance or game zone.

DESCRIPTION OF EXAMPLE EMBODIMENTS Game Systems, Social Networks, andSocial Graphs

In an online multiplayer game, players control player characters (PCs),a game engine controls non-player characters (NPCs) and game features,and the game engine also manages player character state and tracks statefor currently active (i.e., online) players and currently inactive(i.e., offline) players. A player character can have a set of attributesand a set of friends associated with the player character. As usedherein, the term “player character state” can refer to any in-gamecharacteristic of a player character, such as location, assets, levels,condition, health, status, inventory, skill set, name, orientation,affiliation, specialty, and so on. The game engine uses player characterstate to determine the outcome of game events, sometimes alsoconsidering set or random variables. Generally, a player character'sprobability of having a more favorable outcome is greater when theplayer character has a better state. For example, a healthier playercharacter is less likely to die in a particular encounter relative to aweaker player character or non-player character.

A game engine can interface with a social graph. Social graphs aremodels of connections between entities (e.g., individuals, users,contacts, friends, players, player characters, non-player characters,businesses, groups, associations, concepts, etc.). These entities areconsidered “users” of the social graph; as such, the terms “entity” and“user” may be used interchangeably when referring to social graphsherein. The social graph has a node for each entity, and edges torepresent relationships between entities. A node in a social graph canrepresent any entity. The present disclosure assumes that at least oneentity of a social graph is a player or player character in an onlinemultiplayer game, though the present disclosure is intended to cover alltypes of social graph users.

The minimum number of edges required to connect a player or playercharacter) to another user is considered the degree of separationbetween them. For example, where the player and the user are directlyconnected (one edge), they are deemed to be separated by one degree ofseparation. The user would be a so-called “first-degree friend” of theplayer. Where the player and the user are connected through one otheruser (two edges), they are deemed to be separated by two degrees ofseparation. This user would be a so-called “second-degree friend” of theplayer. Where the player and the user are connected through N edges (orN-1 other users), they are deemed to be separated by N degrees ofseparation. This user would be a so-called “Nth-degree friend.” As usedherein, the term “friend” means only first-degree friends, unlesscontext suggests otherwise.

Within the social graph, each player (or player character) has a socialnetwork. A player's social network includes all users in the socialgraph within N_(max) degrees of the player, where N_(max) is the maximumdegree of separation allowed by either the social networking system 520a or the game system 520 b. In one embodiment, N_(max) equals 1, suchthat the player's social network includes only first-degree friends. Inanother embodiment, N_(max) is unlimited and the player's social networkis coextensive with the social graph.

In one embodiment, the social graph is managed by the game networkingsystem 520 b managed by the game operator. In another embodiment, thesocial graph is part of a social networking system 520 a managed by athird-party (e.g., Facebook, Friendster, Myspace, etc.). In yet anotherembodiment, a player has a social network on both the game networkingsystem 520 b and the social networking system 520 a, wherein the playercan have a social network on the game networking system 520 b that is asubset, superset, or independent of the player's social network on thesocial networking system 520 a. In such combined systems, the gamenetwork system 520 b can maintain social graph information with edgetype attributes that indicate whether a given friend is an “in-gamefriend,” a “social network friend,” or both. The various embodimentsdisclosed herein are operable when the social graph is managed by asocial networking system 520 a, a game networking system 520 b, or both.

Out-of-Game and In-Game Social Networks

FIG. 1 shows an example of an out-of-game social network 150 within asocial graph. As shown, Player 101 can be associated, connected orlinked to various other users, or “friends,” within the social network150. These associations, connections or links can track relationshipsbetween users within the social network 150 and are commonly referred toas online “friends” or “friendships” between users. Each friend orfriendship in a particular user's social network within a social graphis commonly referred to as a “node.” The details of social network 150will be described in relation to an original, first, or primary player,e.g., Player 101. As used herein, the terms “player” and “user” can beused interchangeably and can refer to any user or character in an onlinemultiuser game system or social networking system. As used herein, theterm “friend” means any node within a player's social network.

As shown in FIG. Player 101 has direct connections with several friends.When. Player 101 has a direct connection with another individual thatconnection is referred to as a first-degree friend in social network150, Player 101 has two first-degree friends. That is, Player 101 isdirectly connected to Friend 1 ₁ 111 and Friend 2 ₁ 121. In a socialgraph, it is possible for individuals to be connected to otherindividuals through their first-degree friends (i.e., friends offriends). As described above, each edge required to connect a player toanother user is considered the degree of separation. For example, FIG. 1shows that Player 101 has three second-degree friends to which he isconnected via his connection to his first-degree friends. Second-degreeFriend 1 ₂ 112 and Friend 2 ₂ 122 are connected to Player 101 via hisfirst-degree Friend 1 ₁ 111. The limit on the depth of friendconnections, or the number of degrees of separation for associations,that Player 101 is allowed is typically dictated by the restrictions andpolicies implemented by social networking system 520 a.

In various embodiments, Player 101 can have Nth-degree friends connectedto him through a chain of intermediary degree friends as indicated inFIG. 1. For example, Player 101 also has 3rd-degree (e.g., Friend 1 ₃113), and Nth-degree (e.g., Friend 1 _(N) 119) friends. Variousembodiments of the present invention may take advantage of and utilizethe distinction between the various degrees of friendship relative toPlayer 101.

Connections between Player 101 and other entities in the social graphcan be built in several ways. In some embodiments, Player 101 can invitevarious entities into his first-degree level friends category within theinfrastructure of a social network website or other server. In otherembodiments, Player 101 can invite entities to join a social graph ornetwork from within an online multiplayer game. In yet otherembodiments, Player 101 can invite anyone from his out-of-game socialnetwork 150 to join an in-game social network 160 within a separate orconnected online multiuser game.

In various embodiments, a player (or player character) can have a socialgraph within an online multiplayer game that is maintained by the gameengine and another social graph maintained by a separate socialnetworking system. FIG. 1 depicts a schematic example of an in-gamesocial network 160 and an out-of-game social network 150. In thisexample, Player 101 has out-of-game connections 155 to a plurality offriends, forming an out-of-game social network 150. Here, Friend 1 ₁ 111and Friend 2 ₁ 121 are first-degree friends with Player 101 in hisout-of-game social network 150. Player 101 also has in-game connections165 to a plurality of players, forming an in-game social network 160.Here, Friend 2 ₁ 121, Friend 3 ₁ 131, and Friend 4 ₁ 141 arefirst-degree friends with Player 101 in his in-game social network 160.In some embodiments, it is possible for a friend to be in both theout-of-game social network 150 and the in-game social network 160. Here,Friend 2 ₁ 121 has both an out-of-game connection 155 and an in-gameconnection 165 with Player 101, such that Friend 2 ₁ 121. is in bothPlayer 101's in-game social network 160 and Player 101's out-of-gamesocial network 150.

As with other social networks, Player 101 can have second-degree andhigher-degree friends in both his in-game and out of game socialnetworks. In some embodiments, it is possible for Player 101 to have afriend connected to him both in his in-game and out-of-game socialnetworks, wherein the friend is at different degrees of separation ineach network. For example, if Friend 2 ₂ 122 had a direct in-gameconnection with Player 101, Friend 2 ₂ 122 would be a second-degreefriend in Player 101's out-of-game social network, but a first-degreefriend in Player 101's in-game social network.

A multiuser online game can access both in-game social networks 160 andout-of-game social networks 150, and the embodiments disclosed hereinarc operable using either or both.

Implicit and Explicit Friend Connection

In various embodiments, the connections in a player's in-game socialnetwork can be formed both explicitly (e.g., users must “friend” eachother) and implicitly (e.g., system observes user behaviors and“friends” users to each other).

The connection may be explicit when a first user and a second userindicate to the social networking system that the system shouldestablish an edge between their nodes in the social graph. For example,Player 101 can access another player's social network webpage and click“Add as Friend” to establish a friend connection. If the other playeraccepts the friend invitation, the system will record a connectionbetween them on the social graph, thereby expanding the social networksof both players. Both in-game connections 165 and out-of-gameconnections 155 can be formed explicitly.

In various embodiments, the connection can be formed implicitly when thesocial networking system 520 a or the game system 520 b determines thata relationship exists between. to players.

In some embodiments, a multiuser online game may analyze player behavior(which may be synchronous or asynchronous in nature, includinginteractions that may be widely separated in time) and infer friendconnections therefrom. For example, if Player 101 and Friend. 3 ₁ 131have played. Zynga Poker together (e.g., at the same virtual pokertable) for a sufficient period (e.g., twice ever, twice in a month,twice in two days, etc.), the game engine may record the existence of apresumed or implied friend connection between Player 101 and Friend 3 ₁131, even if there is no explicit or express friend connection in thesocial graph.

In some embodiments, in-game friend connections can be determined byreferencing an out-of-game social network 150. For example, if Player101 and Friend 2 ₁ 121 arc friends on out-of-game social network 150(e.g., Facebook), the game engine may presume a friend connectionbetween them and create an in-game connection. 165 in their respectivein-game social networks 160. In some embodiments, a player's in-gamesocial network 160 may comprise the player's entire out-of-game socialnetwork 150 and further comprise additional in-game connections formedexplicitly or implicitly. The game system 520 b may be able tosupplement a player's out-of-network social network 150 by formingout-of-game connections 155 that are implied from game play history. Forexample, if Player 101 and Friend 4 ₁ 141 have played Zynga Poker sixtimes together in the past week but not bothered to “friend” each othereither within the game or within any out-of-game social networks (e.g.,Facebook), the game engine may prompt these players to add each other asfriends on their out-of-game social networks 150, or may evenautomatically create a friend connection between them on the out-of-gamesocial graph.

Similarly, friend connections can be formed programmatically based aplayer's social network information (e.g., friend connections may beimplied between all players in the same geographic area, in the samecompany, or in the same school).

In various embodiments, the game system 520 b may weight differentfactors differently when determining whether to form an implicit friendconnection. For example, the game engine may only imply an in-gameconnection 165 between two players when their “friend factor” exceeds avalue of 1.0, where a bidirectional out-of-game connection between twousers has a value of 0.7, a unidirectional out-of-game connection has avalue of 0.4, and each instance played together has a value of 0.2.Formation of the in-game social network 160 may be aided by a ratingsystem that allows players to provide feedback about other players thatthey have played with. Continuing the example above, giving anotherplayer a positive review has a value of 0.3, while giving that player anegative review has a value of −0.4.

In some embodiments, the in-game social network 160 may be substantiallyconstructed based on prior play experience. That is to say, people withwhom the first user played previously and more frequently become thatuser's friends over time in the view of the game system.

Unless otherwise indicated, reference to a friend connection between twoor more players can be interpreted to cover both explicit and implicitconnections, using one or more social graphs and other factors to inferfriend connections. The friend connections can be unidirectional orbidirectional. It is also not a limitation of this description that twoplayers who are deemed “friends” for the purposes of this disclosure arenot friends in real life (i.e., in disintermediated interactions or thelike), but that could be the case.

Finding Friends for Gaming

Finding Friends for a New Instance

FIG. 2 illustrates an example process 200 for finding friends for gameplay in a new instance.

In various embodiments, Player 101 can submit a request 210 to gamesystem 520 b to play a particular instance of an online multiuser game,to play with one or more players/friends, or both. As used herein, theterms “instance,” “content,” “round of play,” and “single play” may beused interchangeably to refer to a portion of play of an online game.For simplicity, the present disclosure refers to all such play as an“instance” herein. The instance may be discrete (e.g., a number ofrounds), continuous (e.g., until the player is done for that time),constitute art entire sequence of a game (e.g., a round of playingchess), or constitute a subset of a game (e.g., playing five sequentialhands of poker). Player 101 can request to play with another playerfriend explicitly (e.g., via a “Play with Buddy” option) or implicitly(e.g., via a “Play a Round” option, wherein the system finds otherplayers automatically).

In some embodiment, the game engine can consider a variety of game playpreferences provided by a player. For example, in an online poker game,the preferences may include blinds, limits, format, duration, structureof game play, etc. In an RPG, the preferences may include selecting aninstance, zone of play, quest, challenge level, etc.

In response to the request, game system 520 b can access Player 101'ssocial network and analyze 220 the associated social network informationto identify 230 one or more other players for Player 101 to play theinstance with. In some embodiments, game system 520 b will automaticallyidentify other players for Player 101 to play with. In otherembodiments, game system 520 b will prompt Player 101 to choose whetherhe wants to find other players to play with. As used in this section,the terms “social network” may be used to refer to a player's in-gamesocial network 160, the player's out-of-game social network 150, orboth. The game system 520 b can analyze Player 101's social networkuntil sufficient friends are identified 240 for Player 101 to play with.The game system 520 b can analyze other players within Player 101'ssocial network within N_(max) degrees, however optimization or userpreferences may be used to limit this analysis (e.g., only analyzingfirst degree friends, or analyzing until enough friends are found).

In various embodiments, the content of the instance may be private to asubset of players at a given times (e.g., as in various multiuser onlinerole-playing games). In such private instances, changes in state (e.g.,movement of players, actions taken, interactions with each other or theenvironment) for one instance does not change the state of otherinstances of the same game.

Identifying Friends for Play

The game system 520 b can consider a variety of factors to identifyappropriate other players for Player 101 to play the instance with.These factors can be analyzed dynamically and/or algorithmically todetermine which other players to present to Player 101 to play in theinstance.

As appropriate, the game system 520 b can perform this analysis to apredetermined depth (e.g., N-degrees deep) of the player's socialnetwork or, when computationally feasible or desired, the entire socialnetwork can be analyzed to the extent available to the game. In someembodiments, Player 101 can specifically request to only play withfriends from his social. network. Similarly, Player 101 can specificallyrequest to only play with friends within a certain degree in his socialnetwork (e.g., only first or second degree friends).

In some embodiments, the system may preferentially identify thosefriends who have player characters of the appropriate experience, level,or power for the selected instance. For example, if Player 101 wants toplay the Temple of Elemental Evil instance, the game system 520 b mayonly identify friends at step 230 who have player characters that are7th-level or higher. Alternatively, if Player 101 has already tried andfailed to complete that instance, the game system may attempt tocompensate for Player 101's lack of gaming skill and identify friendswho are more powerful than it normally would, e.g., player characterthat are 9th-level or higher.

In some embodiments, the system can analyze Player 101's game play andPlayer 101's social network to make recommendations on additionalfriends to include in the player's social network for improved gameplay, for example to overcome a challenge by a more powerful player orother in-game obstacle that the system has determined has now beeninsurmountable long enough to reduce the player's enjoyment (and thesystem's ability to retain the player as a player) below some criticalthreshold. Continuing the previous example, if Player 101 failed tocomplete the Temple of Elemental. Evil instance on his first try, andPlayer 101 does not have enough friends with 9th-level or highercharacters, the game system may identify other players who have9th-level character but who are not in Player 101's social network.Furthermore, the game system may prompt Player 101 to “add” these otherplayers as friends and form a friend connection in Player 101's socialnetwork. This embodiment may be most useful in multiuser online gamesthat provide a game benefit when a player has friends from his socialnetwork that are also players in the game. For example, if Player 101 isplaying Zynga Mafia Wars and he has 99 friends from Facebook who arealso playing Zynga Mafia Wars, these friends comprise Player 101'sin-game “mob.” The size of the mob provides an in-game benefit. in suchgames, playing with a friend may simply mean adding them to the player'smob.

In some embodiments, the analysis at step 220 may include an analysis ofthe social networks of Player 101's friends. In some games, the size ofa player's social network may provide an in-game benefit. Therefore, thegame system may preferentially identify friends with larger socialnetworks at step 230.

In some embodiments only friends that are actively playing or loggedinto the game are identified at step 230. In other embodiments,inactive/logged-out friends may be identified and these friends can becontacted by the system (e.g., by email, phone, SMS text, etc.) andasked to log in and join the instance. In some embodiments, the gamesystem 520 b can analyze whether friends that are logged in are busy orotherwise unavailable to join a new instance. For some games this may betrivial (e.g., in online poker, players are either in or out of a game).For other games, it may be more difficult for the system toindependently determine if the friend is available or not. The gamesystem can analyze player status updates (reported by facilitiesavailable to the player within the game, or in third-party systems withwhich the game operator's infrastructure may integrate), such as “away,”“afk,” “do not disturb,” “dnd,” etc., can assist the game system inanalyzing which friends are available at steps 220 and 230. Similarly,other algorithms can be used, e.g., to determine if the friend is in aninstance, already in a group, etc. Only available friends are selectedin some embodiments. In other embodiments, friends marked as unavailableare explicitly queried by the game system 520 b to check theirpreference to switch activities. The game system 520 b can similarlyassess the friend's interest, e.g., based on game play preferences thatindicate how much time he has to play, content that interests him, etc.Some of these may be explicitly obtained by querying players at loginwhile others may be implicitly determined based on past behaviors of thefriend. In another embodiment, step 230 only identifies logged in,available friends who have explicitly indicated they want to join aninstance.

One or more of the analyses described above can be use when determiningwhich friends to present for play. These analyses can occur in series orparallel. The types of analyses above arc provided only as examples, andone skilled in the art will also recognize that other analyses areavailable that could be used to identify friends who are available forplay.

Presenting Friends for Play and Content

In various embodiments, once the game system 520 b identifies otherplayers for Player 101 to play with, the game system can then presentthese other players to Player 10.1 at step 250. In some embodiments, theother players are presented to Player 101 by presenting a list of theother players to Player 101, allowing Player 101 to select which otherplayers he wants to play with. In other embodiments, the other playersare automatically selected (e.g., algorithmically) by the game system520 b and presented to Player 101 without any intervention by Player101. Once all the players are selected, the content (e.g., poker, RPGmodule, etc.) is presented to the assembled group for playing at step260. In various embodiments, once the game system 520 b identifies otherplayers for Player 101 to play with, the game system can place Player101 and the other players in an appropriate online play area at step260.

In some instances, more than the required number of friends may beidentified from the analysis of step 220. In those instances, the socialgraph can be used to prioritize the selected friends for the instanceand/or the player can be prompted at step 250 to pick his preferredfriends for this instance. However, additional online players may stillbe required, and steps 220 through 240 can be repeated until sufficientplayers are identified.

As needed or desired, the game system 520 b can also analyze playersoutside of Player 101's social network. For example, if Player 101 wantsto play an instance that requires 8 players but only 3 of his friendsare available, the game system 520 b may identify 5 or more other playeroutside of Player 101's social network to play with Player 101.

During game play, the game system 520 b can monitor each player toanalyze whether a sufficient number of players are still playing theinstance. For example, players could log off, stop playing, or otherwisebecome inactive. If this happens, the game system can determine whetheradditional users are needed at step 270. If the game system 520 bdetermines that more players are needed, process 300 (see FIG. 3) can beperformed to find players to join an ongoing instance.

Identifying the Appropriate Number of Friends for Play

The game system 520 b can consider a variety of factors to determine thenumber of other players it should present to Player 101 at step 250. Forexample, the game system 520 b can consider game engine preferences(e.g., it may be preferred for an active poker game to always have eightplayers), game rules (e.g., a backgammon game must always have twoplayers), player preference (e.g., a RPG player may want a party withfour players), and other factors. In some embodiments, some players maybe NPCs controlled by the game engine.

In some embodiments, steps 220 and 230 are performed in concert with oneanother. For example, Player 101 may have initiated a shootout round inZynga Poker. The game system 520 b will attempt to fill a table with 8players, and currently Player 101 and four of his friends are sitting atthe table, waiting to play. In some embodiments, the game system maytake less than seven of Player 101's friends (e.g., it may startrecruiting players from outside of Player 101's social network to jointhe instance) before initiating the instance, such that the waiting timefrom the request (step 210) the beginning of play (step 260) is keptshort. In various embodiments, the elapsed time from step 210 to step260 is kept below a specified duration, which can range from seconds tominutes to hours. A longer elapsed time may be acceptable if the contentat step 260 is of a longer duration. For example, if a multiuser onlineRPG instance will take four hours, 10-15 minutes to form up a group maybe more acceptable than for a one minute “attack” in another onlinegame. In some embodiments, the game engine can dynamically determine amaximum allowed elapsed time based on the known or approximated durationof the incident.

Finding Friends for Play for an Ongoing Instance

FIG. 3 illustrates an example method 300 for finding friends for gameplay in an ongoing instance. The disclosure of analogous steps inprocess 200 is applicable to process 300.

While the disclosure so far has focused on the formation of a grouparound a player initiating an instance, various embodiments also supportbringing one or more players into an instance that his friends arcalready playing in. This can be helpful when someone drops out of theinstance in the middle of play. For example, if Player 101 and sevenother people are playing online poker and one of them drops out, thegame system 520 b can analyze the social networks of one or more of theremaining players to find friends that can be added to fill the emptyseat.

Process 300 starts with Player 101 playing an ongoing instance that hasinsufficient players. At step 310, it is possible either for a player inon ongoing instance to request that the game system find new players orfor the game system 520 b to automatically determine that it should findnew players. Alternatively, a new player can request to join an ongoinginstance that includes his friends. The request at step 310 may beimplicit or explicit. In some embodiments, process 200 and process 300will execute in parallel and either the player will be joined to a newgame (process 200) or he will be joined to an existing game (process300). For simplicity, process 300 will be described from the point ofview of the players in the ongoing instance who are looking for otherplayers. However, process 300 is also applicable to new players who arelooking to join an ongoing instance, and all steps are analogous.

In various embodiments, the game system 520 b analyzes the social graphsof one or more players in the ongoing instance at step 320. This isgenerally analogous to step 220, however, the analysis may vary. Thegame system. 520 b can analyze whether other players are currentlyavailable, whether the content of the ongoing instance matches otherplayers game play preferences, whether they have player charactersappropriate to play in the ongoing instance, whether they are within acertain depth of the social networks of the players in the ongoinginstance, etc.

Next, the game system 520 b will identify 330 which friends arcavailable for play and present this to Player 101 and/or the otherplayers in the ongoing instance. As with step 230, the game engine canperform a variety of analyses to identify appropriate friends that areavailable for play at step 330. For example, the game system canidentify all friends who are available, only friends who have in-gameconnections 165 with at least two other players in the ongoing instance,only friends who have player characters with appropriate attributes,only friends with appropriate game player preferences, etc. If only onefriend is available, the selection may be automatic. Alternatively, ifone or more friends arc available, then the players in the ongoinginstance may be prompted to select the friend(s) they prefer to join theongoing instance. Similarly, if a player is looking to join an ongoinginstance and multiple appropriate groups are available, that player maybe prompted to select the group he prefers the most.

In some embodiments, the game system 520 b can include communicationtools for contacting friends who arc not “in game” at the time to askthem to come online and play. In one embodiment, the system canexplicitly query friends that are logged into the game (e.g. “Player 101need a friend to help him in the Temple of Elemental Evil join?”). Inother embodiments, based on information other players provided aboutwhether they are generally willing to play an instance, their timeavailable to play, and their available resources, skill, etc., they maybe automatically transferred to an ongoing instance to play with aparticular group even if they never explicitly indicated that they wereinterested in that instance. For example, if Player 101 is logging intothe game, he may automatically be placed in Friend 2 ₁ 121's instancebecause Player 101 and Friend 2 ₁ 121 are friends, and Friend 2 ₁ 121 isalready looking for companions.

Finally, at step 360, the friend is entered into the instance with hisfriends. If players log out of the game or otherwise become unavailable,process 300 can be repeated to find new players for the ongoinginstance.

Poker Example: Zynga Live

FIG. 4 illustrates an example of Zynga Poker with the Zynga Live featurefor finding friends to play online poker with. Here, player John islogged into Zynga Poker and is in the game's “Lobby.” In the Zynga Livedisplay, the game system displays all the friends from John's socialnetwork who are currently also logged in. Here, John only has one otherfriend currently logged in, Fred. The display indicates that Fred isalso currently in the “Lobby” of Zynga Poker. If Fred were currentlyengaged in an instance of poker, it would indicate which poker tableFred was playing at. Furthermore, John would then have the option ofclicking on Fred's icon and joining that same instance of poker. If Johnwants to start a new poker table filled with only his friends, he couldfirst send a message to his friends to let them know he's currentlyplaying Zynga Poker. John could click the “Tell Friends You're Playing”button, and the game system would display a list of friends from John'ssocial network (e.g., Facebook). He could select friends from this list,and the game system would then send a message to them, via the socialnetworking site, informing the selected friends that John is currentlyplaying Zynga Poker and asking them to join.

In another example, the game system 520 b could have John currentlyplaying a game and while the game is ongoing, analyze John's socialnetwork to identify his friends, determine which of those friends areavailable to play poker, and then invite one or more of those friend tothe game by some communication means (e.g., an email or other messagemight pop up saying “Bob: John is currently at Table 7 in Zynga Pokerand there is an empty seat. It will be fun. Can I sit you at that tablewith John and some of her other friends and get you started playing assoon as the next hand is dealt? Press ‘Yes’ and we'll do the rest.”).

Systems and Methods

In the various embodiments, the computer-implemented game may be atext-based or turn-based game implemented as a series of web pages thatare returned after a user selects one or more actions to perform. Inother implementations, the computer-implemented game may be an animatedor rendered game executable as a stand-alone application or within thecontext of a web page or other structured document. In oneimplementation, the computer-implemented game can be implemented usingFLASH(r)-based technologies. For example, the game can be fully orpartially implemented as a SWF object that is embedded in a web page andexecutable by a FLASH(r) media player plug-in. In various exampleembodiments, one or more described webpages may be associated with anetworking system or networking service. However, alternate embodimentsmay have application to the retrieval and rendering of structureddocuments hosted by any type of network addressable resource or website. Additionally, as used herein, a “user” may be an individual, agroup, or an entity (such as a business or third party application).

Particular embodiments may operate in a wide area network environment,such as the Internet, including multiple network addressable systems.FIG. 5 illustrates an example network environment, in which variousexample embodiments may operate. Network cloud 560 generally representsone or more interconnected networks, over which the systems and hostsdescribed herein can communicate. Network cloud 560 may includepacket-based wide area, networks (such as the Internet), privatenetworks, wireless networks, satellite networks, cellular networks,paging networks, and the like. As FIG. 5 illustrates, particularembodiments may operate in a network environment comprising socialnetworking system 520 a, multiuser game networking system 520 b, and oneor more client devices 530. However, a social networking system separatefrom the multiuser game networking system is not necessary. It ispossible for the systems to be combined, such that the social networkingsystem and the multiuser game networking system are part of the samesystem. Consequently, hereinafter, social networking systems 520 a andmultiuser game networking system 520 b may be referred to simply asnetworking system 520. Client devices 530 are operably connected to thenetwork environment via a network service provider, a wireless carrier,or any other suitable means.

In one example embodiment, networking system 520 comprises computingsystems that allow users to communicate or otherwise interact with eachother and access content, such as a multiuser online game, game playerprofiles, social network profiles, and other content as describedherein. Networking system 520 is a network addressable system that, invarious example embodiments, comprises one or more physical servers 522and data stores 524. The one or more physical servers 522 are operablyconnected to computer network 560 via, by way of example, a set ofrouters and/or networking switches 526. In an example embodiment, thefunctionality hosted by the one or more physical servers 522 may includeweb or HTTP servers, FTP servers, as well as, without limitation, webpages and applications implemented using Common Gateway Interface (CGI)script, PHP Hyper-text Preprocessor (PHP), Active Server Pages (ASP),Hyper Text Markup Language (HTML), Extensible Markup Language (XML),Java, JavaScript, Flash, ActionScript, Asynchronous JavaScript and XML(AJAX), and the like.

Physical servers 522 may host functionality directed to the operationsof networking system 520. By way of example, networking system 520 mayhost a website that allows one or more users, at one or more clientdevices 530, to access a multiuser online game, access an online socialnetwork, as well as communicate and interact with one another via thewebsite. Hereinafter servers 522 may be referred to as server 522,although server 522 may include numerous servers hosting, for example,networking system 520, as well as other content distribution servers,data stores, and databases. Data store 524 may store content and datarelating to, and enabling, operation of the networking system as digitaldata objects. A data object, in particular implementations, is an itemof digital information typically stored or embodied in a data file,database or record. Content objects may take many forms, including: text(e.g., ASCII, SGML, HTML), images (e.g., jpeg, tif and gif), graphics(vector-based or bitmap), audio, video (e.g., mpeg), or othermultimedia, and combinations thereof. Content object data may alsoinclude executable code objects (e.g., games executable within a browserwindow or frame), podcasts, etc. Logically, data store 524 correspondsto one or more of a variety of separate and integrated databases, suchas relational databases and object-oriented databases, that maintaininformation as an integrated collection of logically related records orfiles stored on one or more physical systems. Structurally, data store524 may generally include one or more of a large class of data storageand management systems. In particular embodiments, data store 524 may beimplemented by any suitable physical system(s) including components,such as one or more database servers, mass storage media, media librarysystems, storage area networks, data storage clouds, and the like. Inone example embodiment, data store 524 includes one or more servers,databases (e.g., MySQL), and/or data warehouses.

Data store 524 may include data associated with different networkingsystem 520 users and/or client devices 530. In particular embodiments,the networking system 520 maintains a user profile for each user of thesystem 520. User profiles include data that describe the users of anetwork, which may include, for example, proper names (first, middle andlast of a person, a trade name and/or company name of a business entity,etc.), biographic, demographic, and other types of descriptiveinformation, such as work experience, educational history, hobbies orpreferences, geographic location, and additional descriptive data. Byway of example, user profiles may include a user's birthday,relationship status, city of residence, and the like. The system 520 mayfurther store data describing one or more relationships betweendifferent users. The relationship information may indicate users whohave similar or common work experience, group memberships, hobbies, oreducational history. A user profile may also include privacy settingsgoverning access to the user's information is to other users.

Client device 530 is generally a computer or computing device includingfunctionality for communicating (e.g., remotely) over a computernetwork. Client device 530 may be a desktop computer, laptop computer,personal digital assistant (PDA), in- or out-of-car navigation system,smart phone or other cellular or mobile phone, or mobile gaming device,among other suitable computing devices. Client device 530 may executeone or more client applications, such as a web browser (e.g., MicrosoftInternet Explorer, Mozilla Firefox, Apple Safari, Google Chrome, andOpera, etc.), to access and view content over a computer network. Inparticular implementations, the client applications allow a user ofclient device 530 to enter addresses of specific network resources to beretrieved, such as resources hosted by networking system 520. Theseaddresses can be Uniform Resource Locators, or URLs. In addition, once apage or other resource has been retrieved, the client applications mayprovide access to other pages or records when the user “clicks” onhyperlinks to other resources. By way of example, such hyperlinks may belocated within the web pages and provide an automated way for the userto enter the URL of another page and to retrieve that page.

A webpage or resource embedded within a webpage, which may itselfinclude multiple embedded resources, may include data records, such asplain textual information, or more complex digitally encoded multimediacontent, such as software programs or other code objects, graphics,images, audio signals, videos, and so forth. One prevalent markuplanguage for creating web pages is the Hypertext Markup Language (HTML).Other common web browser-supported languages and technologies includethe Extensible Markup Language (XML), the Extensible Hypertext MarkupLanguage (XHTML), JavaScript, Flash, ActionScript, Cascading Style Sheet(CSS), and, frequently, Java. By way of example, HTML enables a pagedeveloper to create a structured document by denoting structuralsemantics for text and links, as well as images, web applications andother objects that can be embedded within the page. Generally, a webpagemay be delivered to a client as a static document, however, through theuse of web elements embedded in the page, an interactive experience maybe achieved with the page or a sequence of pages. During a user sessionat the client, the web browser interprets and displays the pages andassociated resources received or retrieved from the website hosting thepage, as well as, potentially, resources from other websites.

Networking system 520 may include a multitude of features with whichusers at remote clients 530 may interact during user sessions. Inparticular embodiments, these features may be implemented as webapplications and may utilize JavaScript and CSS resources requested fromservers 522 as well as other external servers or data stores. The webapplications or resources may be embedded in various underlying or baseweb pages served to remote clients, such as in frames or &rams, sectionsor “dies” and the like. By way of example, a computer-implemented gamemay be implemented as a FLASH object that is embedded into an HTMLdocument and executable within the context of a client application, suchas a browser. In one such implementation, a game hosted by gamenetworking system 520 b may be embedded into web pages served by socialnetworking system 520 a. In other implementations, game networkingsystem 520 b may serve web pages, including the embedded gameapplication, directly to users.

In particular embodiments, the networking system 520 maintains in datastore 524 a number of objects for the different kinds of items withwhich a user may interact while accessing networking system 520. In oneexample embodiment, these objects include game network user profiles,social network user profiles, application objects, and message objects(such as for wall posts, emails and other messages). In one embodiment,an object is stored by the system 520 for each instance of itsassociated item. These objects and the actions discussed herein arcprovided for illustration purposes only, and it can be appreciated thatan unlimited number of variations and features can be provided on anetworking system 520.

When a user at a client device (e.g., client device 530) desires to viewa particular web page (hereinafter also referred to as target structureddocument) hosted by networking system 520, the user's web browser, orother document rendering engine or suitable client application,formulates and transmits a request to networking system 520. The requestgenerally includes a URL or other document identifier as well asmetadata or other information. By way of example, the request mayinclude information identifying the user, such as a user ID, as well asinformation identifying or characterizing the web browser or operatingsystem running on the user's client computing device 530. The requestmay also include location information identifying a geographic locationof the user's client device or a logical network location of the user'sclient device. The request may also include a timestamp identifying whenthe request was transmitted.

FIG. 6 depicts a schematic of system 600 and data flow between thecomponents of system 600 for operating an online multiuser game. System600 can include a client system 620, a social network server 640 andmultiuser game server 660. Client system 620, social network server 640and multiuser game server 660 can each have a corresponding data storesuch as local storage medium 625, user and social network storage medium645 and game data storage medium 665, respectively. Client system 620can communicate with social network server 640 to receive web pages,messages, etc. Additionally, client system 620 can transmit data to andreceive data from 623 (including game inputs, team displays, datatransfers, etc.) multiuser game server 660. In a similar fashion,multiuser game server 660 and social network server 640 can communicateHTTP packets 643 including data requests, invites, updates, etc. withsocial network server 640. At some other time, or at the same time,social network server 640 can communicate social network data, pageinfo, messages, etc. data 647 with multiuser game server 660. Asmentioned above, communication between client system 620, social networkserver 640 and multiuser game server 660 can occur over any appropriateelectronic communication medium.
